Prototyping process

How to go about prototyping:

1. Identify the base set of requirements

2. Develop the initial prototype

3. Get the prototype reviewed by end-users and customers

4. Based on this review and other work, revise the prototype until it has broad agreement with the customers and end-users



2 main types of prototypes:

1. Evolutionary prototypes: The objective of evolutionary prototyping is to deliver a working system to end-users. Used for systems where the specification cannot be developed in advance such as user interface systems and where verification is impossible because there is no specification.

2. Throw-away prototypes: The objective of throw-away prototyping is to validate or derive the system requirements. Throwaway or Rapid Prototyping refers to the creation of a model that will eventually be discarded rather than becoming part of the finally delivered software. After preliminary requirements gathering is accomplished, a simple working model of the system is constructed to visually show the users what their requirements may look like when they are implemented into a finished system.
